查询词典 two dimensional

In the new method for two-dimensional problems the line integrals onboundary elements are converted into the evaluation of potentialfunctions at the ends of these elements.For three-dimensional cases,thesurface integrals on the usual boundary elements are transformed,through an application of Stokes'theorem,into line integrals on thebounding contours of these elements.

边界轮廓法是刚刚出现的一种新型的边界元法，该方法的核心是利用边界积分方程被积函数散度为零的特性，对二维问题，原积分方程中沿边界单元的线积分被化为单元两端点势函数之差计算，对三维问题，将边界单元上的面积分转变为沿单元轮廓的线积分，它是一种十分简便有效的边界元新技术。

Carl Ludwing explains how this technique differs from traditional texture mapping : when you want something to be in a certain area, like a grease spot, everyone else tends to do it with standard texture-mapping tools. But if I take a painted map and map it on, then I've wrapped a two-dimensional object around a three-dimensional object, and there are all sorts of positioning problems associated with that. Also, when you transition to another subpart of the character, you have to provide a whole new set of coordinates.

卡尔·路德温解释了这一技术与传统材质贴图技术的不同之处，比如说：如果想把油点一类的东西贴到某个地方，别人都会用标准的材质贴图工具来完成，但是如果我先拿来一张着色的地图，把这个油点标在上面，那就等于把一个三维物体安置在二维环境当中，随之会出现各种定位方面的问题，同样，如果你要观察目标的另一处次要部位，就必须给出新的坐标。
